I have a John deere 4045 common rail,with denso pump,and also a three plug ecm on the side of the engine. Not sure what the engine came out of, but I would like to know if it will run. So the question is what of the ecm do I need to power up and ground or what can I do just to see if it will run before I decide what to do with it. Thanks in advance
Welcome to HEF Kolby ! For me to answer that question, I will need the complete engine serial number. Post a picture of the ECU tag as well, if it is legible.

Thanks I'll see what I can do with the diagram tomorrow when I get back to the engine. I appreciate all the help
